      Hi there,

      I ordered a M203+xS10 some months ago, and I'm finally ready to start using them in my rebuilt house.
      Testing with the EVOK image and measuring the devices, I notice a permanent 1-2 volts between the DOGND and DO1.1 - 1.4. Enabled the voltage drops to 0,599 V.
      I expected measuring 0V when they are inactive, and something between 10-24Volts when they are active.

      Am I wrong ? Did I misunderstood the DO's ? Or do I possibly have a faulty unit ? Or could it be a software problem ? (Running UniPian-Neuron-OS-2018-03-09)

      Thanks for your answers!!

        Hi @stevenbrs,

        The DOs are NPN type (open collector), check the documentation for proper wiring. Everything is OK with your HW and SW, do not worry.
